Ethernet Port Leds On The System Board; Ethernet Port Leds On A 10 Gbps Ethernet Adapter - IBM SAN Volume Controller 2145-SV1 Hardware Installation Manual

Figure 9. Ethernet port LEDs on the system board
1 Ethernet link LED
2 Ethernet activity LED
The Ethernet-link LED indicates that the node is communicating on the network that is connected to the
port. The Ethernet-activity LED indicates an active connection on the port.
Ethernet ports on a 10 Gbps Ethernet adapter
If the SAN Volume Controller 2145-SV1 is equipped with a 10 Gbps Ethernet adapter, the port activity is
not reflected on the activity LEDs of the operator-information panel. The activity of those ports is
indicated by LEDs on the adapter itself, which are visible from the rear of the SAN Volume Controller
2145-SV1 (as shown in Figure 10 on page 10). The adapter has two LEDs per port, arranged above the
other. These pairs of LEDs are arranged in the same order as the ports.

Ethernet ports on a 25 Gbps Ethernet adapter
The SAN Volume Controller 2145-SV1 node can support optional 2-port 25 Gbps Ethernet adapters. The
system can support RoCE and iWARP networking adapters only for 25 Gbps iSCSI connectivity. LEDs
indicate the activity on the ports on each adapter; however, the location and meaning of the LEDs differs,
depending on the type of 25 Gbps card that is installed.
Figure 11 on page 11 shows an example of the RoCE networking adapter. Each port on the 2-port 25
Gbps Ethernet adapter has one bi-color LED that indicates the status of the link.
